To all whom t may concern.'

Be it known that I, ROBERT HOPE-JONES,

in the count of N'- `agara and State of New York, have invented certainnew anduseful .Improvements in Automatic Door-Operating Mechanism; and Ido hereby declare the following to be a and exact description of thesame, reference being had to the accompanying drawings, forming a partof the specification, and to the reference-numerals marked thereon. v

The present invention has for its object to provide a mechanism forautomatically operating doors and-adapted particularly to be used inconnection with multipanel revolving doors, whereby the latter maybecaused to move in advance of the operator.

A further object of my invention is to p rovide an operating or drivingmechanism adapted to operate intermittently and con` trolling devicestherefor actuated by the operator for setting said mechanism intooperation or arresting it, as may be required.

To these and other ends the invention consists in certain improvementsand combinaparts all as will be hereinafter more fully described, thenovel features being pointed out inthe claims at the end of thespecification. l .In the drawings: Figure l is a side elevationypartly-inv section of a revolving door provided with operating andcontrolling mechanism constructed in accordance with my invention, Fig.2 is a top plan view thereof; Fig. 3 is a detail diagrammatic thecircuit larrangement of the controlling mechanism; and Fig. 4 is asectional view taken on the line IX-4* of Fig. 1,l showing one of thecontact making members.

lower end in ra ity. .of panels, dicated .by A,

doors lradiate from a central shaft G on which theyare supported, saidshaft being ournaled near its upper end and at the the top H and thebottom I of the casing. In the operation of doors of this and arrestedare mounted upon the top H Fig. 2. The several character a personstepping into the casing at one side or the other pushes the door orpanel immediately in front of him, such as the door A or C, causing allof the doors to revolve until the particular panel which is ahead of himpasses beyond the segmental side of the casing and rovides an exitspace. In the construction o doors of this character it is customary toemploy four panels which are arranged at right angles to each other andin order to provide ample space for the accommodation of an adult personand permit him to walk through the casing and use his normal length ofstep, it is necessary to make the doors of considerable Width and inorder to obtain a substantial structure, the doors are necessarily quiteheavy. It is also customary to provide the doors with plate glass panelsand in many instances, especially in the more ornamental structures, theframe work or sash is made wholly of metal, consequently the structureas a Whole is ponderous and somewhat dificult to operate, especially ifthe door is in position of rest and each person desirin to pass throughthe doorway is require to start it in motion.

To facilitate the operation of the door, so that it may be rotated-intermittently at the volition of the operator, I have provided anoperating mec anism which will be actuated whenever he attempts to pusha dooi ahead of him and the controlling devices by which the drivingmechanism 1s started so arranged that the door or doors will continue torevolve as long as the operator follows it in the direction of itsmovement and exerts a slight pressure upon the operating member. Thecontrolling devices also embody an arresting memI ber which is throwninto operation in the event the person operating the door should halt orso retard his movement that the door following him engages a In carryingout my invention I have of the door casing a driving mechanismconsisting of a worm 1 and a gear wheel 2, the former being driven fromany convenient source of power,: preferably an electric motor, indicatedby 3.

he gear wheel 2 is journaled loosely upon the upwardly projecting end ofthe vertical door shaft G and imparts rotary movement thereto 'in onedirection by means of a ratchet wheel 4 keyed to the shaft with portionof his body.

which a driven connection is maintained by means of a spring operateddog or pawl 5, this connection causing the doors to be moved in onedirection and also permitting them to move in the same direction at anincreased rate of speed, should an operator impart momentum to the doorsgreater than the rate of speed at which they may be operated by thedriving devices. Also mounted on the shaft Gr and rigidly connect- -edthereto is a brake wheel 6 encircled by a brake band 7, one` end ofwhich is connected, as indicated at 8, to an arm 9 of a bell crank lever11, its opposite extremit 10 being attached to an arm 9i of the ellcrank lever whiclnispivoted. at 12 to the bracketl cured to the shaft Gis a disk 17 of insullating material provided on one of its faces withconcentric collector rings 18, 19 and 20 with which respectively engagewipers or brushes 21, 22 and 23 pivotally supported in stationarybrackets 24, 25 and 26 secured to the top H of the door casing. Theshaft G is preferablyl tubular and passing down' vvardly therethroughare the conductors 18", 19x and 20X fromeach 'of which leadva pluralityof branch wiresconnected to the contacts controlled by the operating andarresting plates or ,members mounted on the several door panels, as willbe further described.

Arranged on the rear face of each dooror panel is the operating memberor push plate,

indicated in the diagrammatic illustration Fig.` 3 by the referenceletters A', B, C and D. In the forward face of each door is a similarplate which maybe located at any desired position to engage some portionof the body ofa person with which it may be brought into contact, but.preferably arranged at the lower or bottom edge of the door in suchposition -that 1t may be actuated byfengagement with a persons heel inthe event their step is faulty or retarded. In Fig. 3 these arrestingmembers are lndicated by A2, B2, Czand D2. The detail construction ofthe members just referred to is shown in Fig. 4. The operating membersor push plates are preferably arranged in recesses in the rear faces ofthe doorpin which they Vare yieldingly supported by springs 27 normallytending to project them into engagement with the overlapping edges of'the stop plates 28. Within the door re` cessis a block 29 of insulatingmaterial through the center of which passes a stud 30 in electricalconnection with a leaf spring in the present instance.

having the ends 31 and' carrying insulating studs 33, 34, and adapted toengage the vcontact points 35 and 36 which are als'osup- From ported onthe insulating block 29. this arrangement of the parts it will be seenthat slight pressure applied uponthe plate or member A will move thelatter inwardly against the tension of either or both of the springs 27permitting the contact spring at one or both ends to engage the contacts35 and 36. Thepush plateV may be guided upon studs or pins, as indicatedat 37.

`The push plates just described are adapted to close the circuit of thedoor operating motor either directly or by closing an auXiliary circuitprovided With an electromagnetic device for causing the operation of themotor, the latter arrangement being shown On referring now to thediagrammatic figure of the drawings, 1 have there illustrated theduplication of various contacts referredto in the descrip'- tion of Fig.4 as they appear on the several door panels and in each case-they areindicated by the numerals before applied, but each of these is suppliedwith the proper exponentl a, b, c, orV d, according to the particularpanel A, B, C` or D on which the parts are respectively located.' 1nthis illustration-it will be seen that the conductor 18x is connected bythe wires 180,' 181, 182 and v with the contacts 35-36,

of .the sets lof normally openvcontacts operated by the sev- Current foroperating the motor 3 be obtained from any suitable source supplied overthe line wires X and Y,I and interposed y in the circuit between thesource supply and the motor is a normally open switch comprising thecontacts 40 and 41, the latter being mounted on the switch4arm`42piv'oted on .the binding post 43 and retracted into inoperativeposition by a spring 44. Leading from the line wire Y to the contact 40is a conductor y and from the binding post 43v to one ofthe brushes ofthe motor 3 is'the conductor y which is continued fromxthe other brushof the motor, as indicated at 2, to a contact ys which is normallyengaged by aspring contact plate y* carried by the brake operating lever13. The contact plate yi isconnected to the linewire X by the conductorw.- l

The switch arm 42 for closing the motor circuit is actuated by themagnet or solenoid 45, the armature or core 46 of which is con-- nectedto the switch arm 42. One terminal, of ythe solenoid 45 is connected tothe line wire Y by a conductor m2 and from the othei tacts on the doorsare,

terminal thereof a conductor w3 leads to the brush 21, which bears onthe ring 18. The line wire X is connected by a conductor m4 to the brush22 which bears on the ring 19. The conductors 1 v#519" leading to theconas previously described, connected to the collector rings 18 and 19,'fromV this it will be seen that the solenoid 45 isl arranged in acircuit comprisi g all of the various sets of contacts, so that it maybe energized by pressure upon vany one of the push plates, as will beunderstood.

The energizing of the solenoid 45 effects the `operation of the switchL12 and the closing of the motor circui .The operation of the mechanismso far described, will now be clearly understood. A
